[MS]Remove multiple spaces

Given a string with multiple delimiters in between words,you have to replace them with single space.
eg:"       hello\t\t   hii    " is changed as " hello hii ".

  1. delimiters includes just spaces and tab?

  3. then we can do it using queue.we keep on adding elements to the queue until we encountered delimiter.once a delimiter is encountered we just add a space in the queue ans skip all the delimiters...the process has to be repeated till we reach end of string

  4. @anonymous this should be done in a single parsing without using any extra space..:)

  5. Using counter :

    char *remove_ts(char *str)
    {
    int i,z,count;
    for(count=i=z=0;str[i];i++){
    if(str[i]=='\t'||str[i]==' ')
    count++;
    else{
    if(count){
    str[z]=' ';
    z++;
    }
    str[z]=str[i];
    z++; count=0;
    }
    }
    str[z]='\0';
    return str;
    }

  6. @Trent yes your code will work fine except the case when string ends with multiple delimiter then in that case you will never enter else statement.so you should put count condition at the end before adding str[z]='\0'.please check..:)

  7. yes i forgot that the last can be a space!
    here a fix before str[z]='\0' :

    if(str[i-1]==' '){str[z]=' '; z++;}
